How Big Do Bearded Dragons Grow

Bearded dragons are popular reptile pets known for their unique appearance and friendly demeanor. Before getting a bearded dragon as a pet, it is important to understand how big they can grow and what factors can influence their size. In this article, we will explore the average size of bearded dragons, the factors that can affect their growth, and how to ensure they reach their maximum potential size.


Bearded dragons, scientifically known as Pogona vitticeps, are native to Australia and have become increasingly popular as pets around the world. These reptiles are known for their spiky appearance, which resembles a beard, and their calm and docile nature. One crucial aspect of bearded dragons that potential owners should be aware of is their growth potential. Understanding how big bearded dragons can grow is essential for providing them with proper care and accommodation. In this article, we will delve into the factors that influence their size and how to ensure their healthy growth.

Factors Affecting Bearded Dragon Growth

Several factors can influence the growth and size of bearded dragons. These factors include genetics, nutrition, housing conditions, and overall health. Let's explore each of these factors in more detail:


Just like with humans and other animals, genetics play a significant role in determining the size of bearded dragons. Different bearded dragon morphs, or genetic variations, can impact their growth potential. For instance, some morphs may naturally grow larger than others, while some may have a slower growth rate. The genetics of a bearded dragon can influence its size, coloration, and overall appearance.


Proper nutrition is crucial for the healthy growth of bearded dragons. These reptiles are omnivores, meaning they eat both plants and animals. A well-balanced diet consisting of vegetables, fruits, insects, and occasionally small vertebrates is necessary to ensure they receive all the essential nutrients, vitamins, and minerals they need to grow. Providing a varied diet that replicates their natural food sources is essential for their healthy growth.

Housing Conditions

The environment in which a bearded dragon lives can also impact its growth. Bearded dragons require a suitable habitat that provides enough space for them to move around and explore. The size of the enclosure should be adequate for their growth potential. A cramped or small enclosure can limit their movement and result in stunted growth. Additionally, providing proper heating and lighting is essential to maintain their overall health and promote healthy growth.

Overall Health

The overall health of a bearded dragon is crucial for its growth. Any underlying health issues, such as metabolic bone disease or parasites, can hinder their growth potential. Regular visits to a reptile veterinarian, along with routine health checks, can help identify and address any health concerns. Providing a clean and stress-free environment, along with regular exercise, can contribute to their overall well-being and promote healthy growth.

Average Size of Bearded Dragons

The size of bearded dragons can vary depending on several factors, including their age, sex, and overall health. On average, male bearded dragons tend to be slightly larger than females. However, both sexes can reach impressive sizes under optimal conditions. Let's take a look at the average sizes for different age groups of bearded dragons:


When bearded dragons hatch from their eggs, they are typically around 3 to 4 inches (7.6 to 10.2 cm) in length, including their tail. At this stage, they are fragile and require extra care to ensure their survival. The size of hatchlings can vary slightly depending on individual genetics and the conditions in which they were incubated.


As bearded dragons enter their juvenile stage, their growth rate tends to be rapid. Between the ages of 2 to 6 months, they can grow up to an inch (2.5 cm) per week. By the time they reach 6 months of age, they can measure around 12 to 16 inches (30.5 to 40.6 cm) in length, including their tail. Proper nutrition and housing conditions are crucial during this stage to support their rapid growth.

When bearded dragons reach the sub-adult stage, their growth rate starts to slow down. Between 6 to 18 months of age, they continue to grow but at a more gradual pace. At this stage, they can measure around 16 to 20 inches (40.6 to 50.8 cm) in length, including their tail. The growth rate during this stage can vary depending on individual genetics and overall health.


Fully grown adult bearded dragons can reach an average length of 18 to 24 inches (45.7 to 61 cm), including their tail. However, some individuals may exceed these measurements and grow even larger. The size and weight of adult bearded dragons can also vary depending on their genetics, overall health, and the care they receive.

Ensuring Maximum Growth Potential

To ensure that your bearded dragon reaches its maximum growth potential, it is essential to provide them with optimal care and conditions. Here are some tips to help promote healthy growth in your bearded dragon:

1. Proper Nutrition: Providing a well-balanced diet that consists of both plant matter and protein sources is crucial for their growth. Feed them a variety of vegetables, fruits, and insects to ensure they receive all the necessary nutrients.

2. Suitable Housing: The enclosure for your bearded dragon should be spacious enough to allow for movement and exercise. A minimum size of 40 gallons is recommended for adult bearded dragons, but larger enclosures are preferable. Ensure the enclosure is properly heated and has the appropriate lighting to support their growth.

3. Regular Veterinary Visits: Regular check-ups with a reptile veterinarian can help identify and address any health concerns that may hinder their growth. A veterinarian can also provide guidance on their diet, supplements, and overall care.

4. Stress Reduction: Bearded dragons can become stressed in certain situations, which can affect their appetite and growth. Provide them with a calm and quiet environment, minimize handling if it causes stress, and provide hiding spots within their enclosure to help reduce stress levels.
